    1. WiFi Direction

DLOS8N use directional WiFi Antenna. The best direction is as below:


  1.  Access and Configure DLOS8N

The DLOS8N is configured as a WiFi Access Point by default. User can access and configure the DLOS8N after connecting to its WiFi network, or via its Ethernet port.

    1. Find IP address of DLOS8N
      1. Connect via WiFi


file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image008.png At the first boot of DLOS8N, it will auto generate a WiFi network called dragino-xxxxxx with password:


User can use a PC to connect to this WiFi network. The PC will get an IP address 10.130.1.xxx and the DLOS8N has the default IP

      1. Connect via Ethernet with DHCP IP from router


Alternatively, connect the DLOS8N Ethernet port to your router and DLOS8N will obtain an IP address from your router. In the router’s management portal, you should be able to find what IP address the router has assigned to the DLOS8N. You can also use this IP to connect.

      1. Connect via WiFi with DHCP IP from router


If the DLOS8N already connect to the router via WiFi, use can use the WiFi IP to connect to DLOS8N.

      1. Connect via Ethernet with fall back ip

The WAN port also has a fall back ip address for access if user doesn’t connect to uplink router. Click here to see how to configure.

    1. Access Configure Web UI

Web Interface

Open a browser on the PC and type the DLOS8N ip address (depends on your connect method)  (Access via WiFi AP network)

  1.  Typical Network Setup
    1.  Overview

The DLOS8N supports flexible network set up for different environments. This section describes the typical network topology. The network set up includes:

  • WAN Port Internet Mode
  • WiFi Client Mode
  • WiFi AP Mode
  • Cellular Mode
    1.  Use WAN port to access Internet

By default, the DLOS8N is set to use the WAN port to connect to an upstream network. When you connect the DLOS8N’s WAN port to an upstream router, DLOS8N will get an IP address from the router and have Internet access via the upstream router. The network status can be checked in the home page:


    1.  Access the Internet as a WiFi Client.

In the WiFi Client Mode, DLOS8N acts as a WiFi client and gets DHCP from an upstream router via WiFi.

The settings for WiFi Client is under page System à WiFi  à WiFi WAN Client Settings


In the WiFi Survey Choose the WiFi AP, and input the Passphrase then click Save & Apply to connect.

    1. Access the Internet via Cellular

If the DLOS8N support 3G/4G Cellular modem option, When the label on the shell is displayed as Model : DLOS8N-EC25, it indicates that DLOS8 already has EC25 3G/4G modules,user can use it as main internet connection or back up.

First, release the four screws of DLOS8N, pull out PCB and install SIM card as below:



The set up page is System à Cellular

While use the cellular as Backup WAN, device will use Cellular for internet connection while WAN port or WiFi is not valid and switch back to WAN port or WiFi after they recover.


Note *: For DLOS8N which doesn’t have the cellular module, this page will shows Cellular not detected.

    1. Check Internet connection

In the Home page, we can check the Internet connection.

  • GREEN Tick  file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image017.png   : This interface has Internet connection.
  • Yellow Tick file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image018.png : This interface has IP address but don’t use it for internet connection.
  • RED Cross file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image019.png : This interface doesn’t connected.


  1. Example: Configure as a LoRaWAN gateway

DLOS8N is fully compatible with LoRaWAN protocol. It uses the legacy Semtech Packet forwarder to forward the LoRaWAN packets to server. The structure is as below.


This chapter describes how to use the DLOS8Nto work with

TheThingsNetwork v3(TTN v3) LoRaWAN Server  (www.thethingsnetwork.org)

    1.  Create a gateway in TTN V3 Server

Step 1: Get a Unique gateway ID.

Every DLOS8N has a unique gateway id. The ID can be found at LoRaWAN page: 


The example gateway id is: a840411e96744154

Step 2: Sign up a user account in TTN server



Step 3: Choose the TTNv3 Cluster Picker


Note: Choose the cluster corresponds to a specific Gateway server address

  • Europe 1 corresponding Gateway server address: eu1.cloud.thethings.network
  • North America 1 corresponding Gateway server address: nam1.cloud.thethings.network
  • Australia 1 corresponding Gateway server address: au1.cloud.thethings.network
  • Legacy V2 Console : TTN v2 shuts down in December 2021

Step 4: Create a Gateway


Click the Gateway icon and then click Add gateway.

Open the following page:

 file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image026.png  file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image027.png

Notice: Gateway Server address must match the gateway configuration, otherwise you will have problem for End Node to join the network.

After creating the gateway, you can see the gateway info, as below.


    1.  Configure DLOS8N to connect to TTN v3

You can now configure the DLOS8N to let it connect to TTN network V3.

Make sure your DLOS8N has a working Internet Connection first.

Choose the right server provider and click Save&Apply


Note: The server address must match the Gateway server address you choose in TTN V3.

In the home page, we can see the LoRaWAN connection is ready now.


In TTN v3 portal, we can also see the gateway is connected.


    1.  Configure frequency

We also need to set the frequency plan in DLOS8N to match the end node we use, so to receive the LoRaWAN packets from the LoRaWAN sensor.


In logread page, user can check the frequency actually used.


    1.  Add a LoRaWAN End Device

This section shows how to add a LoRaWAN End device to a LoRaWAN network and see the data from TTN web site.

We use LT-22222-L IO Controller as a reference device - the setup for other LoRaWAN devices will be similar.


Step 1: Create a Device definition in TTN v3 with the OTAA keys from the example LT-22222-L IO Controller device.

Three codes are required to define the device in TTN v3:

  • DEV EUI - Unique ID code for a particular device.
  • APP EUI - ID code for an Application defined in TTN v3.
  • APP Key - Unique key to secure communications with a particular device.

A set of these codes are stored in each device by the manufacturer as the default codes for that particular device. Each device is shipped with a sticker with the default Device EUI as shown below.


Note: You may be able to change these codes in a device by using a configuration facility on the device e.g. the LT-22222 uses a serial port access and a series of AT commands.  Changing the codes may be necessary in the case where you have to use codes assigned by a LoRa WAN server.

For the TTN v3 server, you can use the codes set in the device as in the following example.

Select Add Application to open the screen below.


Open the Application select Add end device

Start Register the end device


Select OTAA activation mode

The LoRaWAN version for your device should be provided by the manufacturer in a datasheet as LoRaWAN version or LoRaWAN specification. The most commonly used LoRaWAN versions are v1.0.2 and v1.0.3.


First, input the End device ID, AppEUI and DevEUI.


Secondly, choose the corresponding frequency and LoRaWAN class capabilities.


Finally, Application layer settings input the corresponding AppKey. Before saving the configuration, check that the data matches the device.

Step 2: Power on LT-22222-L device and it will automatically join the TTN network. After joining successfully, it will start to upload messages to the TTN v3. Select the Live data tab and you will see the data appearing in the panel.

Note that it may take some time for the device data to appear in the TTN v3 display.

    1. More instructions


  1.  Linux System

The DLOS8N is based on the OpenWrt Linux system. It is open source, and users are free to configure and modify the Linux settings.

    1.  SSH Access for Linux console

User can access the Linux console via the SSH protocol. Make sure your PC and the DLOS8N are connected to the same network, then use a SSH tool (such as putty in Windows) to access it.

IP address:  IP address of DLOS8N

Port:         22 (via WiFi AP mode) or 2222 (via WAN Interface)

User Name:      root

Password:         dragino (default)

After logging in, you will be in the Linux console and can enter commands as shown below.


The “logread -f” command can be used to debug how system runs.


    1.  Edit and Transfer files

The DLOS8N supports the SCP protocol and has a built-in SFTP server. There are many ways to edit and transfer files using these protocols.

In Windows, one of the easiest methods is using the WinSCP utility.

After establishing access via WinSCP to the device, you can use an FTP style window to drag / drop files to the DLOS8N, or edit the files directly in the windows.

Screenshot is as below:


    1.  File System

The DLOS8N has a 16MB flash and a 64MB RAM. The /var and /tmp directories are in the RAM, so contents stored in /tmp and /var will be erased after rebooting the device. Other directories are in the flash and will remain after reboot.

The Linux system uses around 8MB ~10MB flash size which means there is not much room for user to store data in the DLOS8N flash.

You can use an external USB flash memory device to extend the size of flash memory for storage.

    1.  Package maintenance system

DLOS8N uses the OpenWrt OPKG package maintenance system. There are more than 3000+ packages available in our package server for users to install for their applications. For example, if you want to add the iperf  tool, you can install the related packages and configure DLOS8N to use iperf .

Below are some example opkg  commands. For more information please refer to the OPKG package maintain system (https://wiki.openwrt.org/doc/techref/opkg)

In Linux Console run:

root@dragino-169d30:~# opkg update  // to get the latest packages list

root@dragino-169d30:~# opkg list         //shows the available packages

root@dragino-169d30:~# opkg install iperf // install iperf

The system will automatically install the required packages as shown below.

root@dragino-169d30:/etc/opkg# opkg install iperf

  1.  Upgrade Linux Firmware 
  1.  FAQ
    1.  How can I configure for a customized frequency band?

See below link for how to customize frequency band:


    1. Can I connect DLOS8N to LORIOT?

Yes, the set up instruction is here: http://wiki.dragino.com/index.php?title=Notes_for_LORIOT

    1.  Can I make my own firmware for the gateway, where can I find the source code?

Yes, You can make your own firmware for the DLOS8N for branding purposes or to add customized applications.

The source code and compile instructions can be found at: https://github.com/dragino/openwrt_lede-18.06

    1.  Can I use 868Mhz version for 915Mhz bands?

It is possible but the distance will be very short, you can select US915 frequency band in 868Mhz version hardware. It will work but you will see the performance is greatly decreased because the 868Mhz version has an RF filter for band 863~870Mhz, all other frequencies will have high attenuation. 

  1.  Trouble Shooting
    1.  I get kernel error when install new package, how to fix?

In some cases, when installing a package with opkg, it will generate a kernel error such as below due to a mismatch I the kernel ID:

root@dragino-16c538:~# opkg install kmod-dragino2-si3217x_3.10.49+0.2-1_ar71xx.ipk

Installing kmod-dragino2-si3217x (3.10.49+0.2-1) to root…

Collected errors:

* satisfy_dependencies_for: Cannot satisfy the following dependencies for kmod-dragino2-si3217x:

*      kernel (= 3.10.49-1-4917516478a753314254643facdf360a) *

 * opkg_install_cmd: Cannot install package kmod-dragino2-si3217x.

In this case, you can use the –force-depends option to install such package as long as the actual kernel version is the same.

Opkg install kmod-dragino2-si3217x_3.10.49+0.2-1_ar71xx.ipk –force-depends

    1.  How to recover the DLOS8N if the firmware crashes

Please follow this instruction to recover your gateway:


    1.  I configured DLOS8N for WiFi access and lost its IP. What to do now?


The DLOS8N has a fall-back IP address on its WAN port. This IP is always enabled so you can use the fall-back IP to access DLOS8N no matter what the WiFi IP is. The fall back IP is useful for connecting and debug the unit.

(Note: fallback IP can be disabled in the WAN and DHCP page)

Steps to connect via fall back IP:

  1. Connect PC’s Ethernet port to DLOS8N’s WAN port
  2. Configure PC’s Ethernet port has
    IP: and

As below photo:
